DETAILED DESCRIPTION OF THE DISCLOSURE

To make the objective, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further detailed with reference to specific embodiments thereof and the attached drawings. It is understood that the embodiments of the present invention are elaborated to construe the present invention, and not to limit technical solutions of this application.
Referring to FIG. 1, according to one embodiment of the present disclosure, a wireless pairing system 100 is provided, the system 10 includes an emitting terminal 12 and a receiving terminal 14. In realistic practice, more than one emitting terminal 12 and more than one receiving terminal 14 can be adopted, therefore, for a specific emitting terminal/receiving terminal. A preceding pairing process should be carried out between the specific emitting terminal/receiving terminal and an available receiving terminal/emitting terminal. Only after the preceding pairing process, can the emitting terminal communicate with the receiving terminal.
It should be noted that the terms in present disclosure “emitting terminal” and “receiving terminal” are not restricted only referring to a terminal of transmitting or a terminal of taking over. The emitting terminal can accept communicating signals at some stage, the communicating signals include but not limited to feedback signals sent by a receiving terminal. The receiving terminal can send communicating signals at some stage, the communicating signals include but not limited to feedback signals and so on from a receiving terminal indicating to the emitting terminal a refusal or an acceptance.
Referring to FIG. 1, the emitting terminal 12 includes an emitting terminal storage unit 120, a traversal unit 122, a pairing unit 124, and an emitting terminal wireless transceiver 126.
Wherein, the emitting terminal storage unit 120 is used for storing an identifier list of receiving terminals with information of receiving terminals 14 having been paired with emitting terminals 12 in history record. In real practice, the emitting terminal 12 and the receiving terminal 14 are usually arranged in a set matching. In a nonrestrictive embodiment, the emitting terminal can be a wireless speaker, and the receiving terminal can be a smartphone, notebook, palmtop, etc. In general, according to customer habits, the wireless speaker normally set up a communication connection by blue tooth module of a smartphone. Therefore, it is preferred that an identifier list of receiving terminals is stored in the wireless speaker, for recording a list of receiving terminals having been paired with the wireless speaker in history record.
The traversal unit 122 is adapted to send matching requests to the receiving terminals 14 in the identifier list of receiving terminals successively, until the emitting terminal wireless transceiver 126 receives a matching response.
Preferably, the traversal unit 122 is further adapted to sort receiving terminal identifiers in the identifier list of receiving terminals, according to time tab corresponding to each receiving terminal identifier. The time tab is a history pairing time between the receiving terminal and the emitting terminal in accordance with relating receiving terminal identifier, and the sorting is carried out on the basis of interval values between a history pairing time and a current time in smallest to largest order. It should be noted that if an emitting terminal 12 has been paired with a receiving terminal 14 for many time in history, the receiving terminal 14 is only recorded once in the identifier list of receiving terminals. Time tab corresponding to the receiving terminal is the history pairing time when the receiving terminal is paired with the emitting terminal at last time. Regarding the embodiment with the above described wireless speaker, receiving devices having been paired ever are recorded in the wireless speaker, such as smartphone, laptop, palmtop and so forth, and only the last history pairing record are stored.
It is further noted that although the traversal unit 122 sorts the identifier list of receiving terminals in the above illustration. In another embodiment, the identifier list of receiving terminals is sorted according to recent history pairing time between the receiving terminals in the list and a specific receiving terminal. The traversal unit 122 sends matching requests in accordance with chronological order of history paring time to the receiving terminals in the identifier list of receiving terminals in last pairing process.
The pairing unit 124 is adapted to transmit coupling requests to detectable receiving terminals on condition that the emitting terminal wireless transceiver 126 receives no matching response returned by the receiving terminal within a first preset time. In detail, it would be described that when the emitting terminal 12 send out a matching request, and after the receiving terminal 14 takes over the matching request, the receiving terminal 14 would return a matching response to the emitting terminal wireless transceiver 126 of the emitting terminal 12 which sends out the matching request. Therefore, a preset duration is needed, for example, 6 seconds, in the preset duration, (from the moment the traversal unit 122 starts to send matching request). If no matching response received, it means that all of receiving terminals in the identifier list of receiving terminals receives or accept no matching request. At this moment, the emitting terminal 12 initiates a generic pairing mode, i.e., the pairing unit 124 sends out coupling requests to all detectable receiving terminals 14, until a coupling response is received.
It is noted that the preset duration is determined based on length of identifier list of receiving terminals and processing speed of the system 10, as long as the emitting terminal 12 can send out matching requests to all receiving terminals in the identifier list of receiving terminals within the preset duration.
In another embodiment, in the generic pairing mode, the pairing unit 124 successively sends out coupling requests to detectable receiving terminals. It is preferred that in each pairing process, after a preset time the pairing unit 124 send out a coupling request to a receiving terminal 14 available for connection, it is need that the emitting terminal wireless transceiver 126 is detected a receipt of a matching response; if no matching response received, go on generic pairing.
The emitting terminal wireless transceiver 126 is adapted to detect receipts of matching responses or coupling responses, on condition of receipts of a matching response or a coupling response, to determine the receiving terminal 14 corresponding to received matching response or received coupling response as a target receiving terminal, and to set up a communication connection with the target receiving terminal.
In a preferred embodiment, the pairing unit 124 is further adapted to send coupling requests in a second preset time to detectable receiving terminals, and to cease sending coupling requests to detectable receiving terminals in condition of no coupling response received by the emitting terminal wireless transceiver 126.
In detail, it is presumed that the second preset time is 60 seconds, it means that the system 10 will assign 60 seconds to the pairing unit 124 to send coupling requests, if the emitting terminal wireless transceiver 126 receives no coupling response within the 60 seconds. It is inferred that no receiving terminal 14 receives or accepts the coupling requests, and the coupling request process is failed. For energy source saving purpose, stop emitting coupling requests.
It is further preferred that the traversal unit 122 is further adapted to transmit matching requests successively to receiving terminals 14 in the identifier list of receiving terminals again, when a third preset time is up after the pairing unit 124 ceases sending coupling requests to the detectable receiving terminal, until the emitting terminal wireless transceiver 126 gets a matching response.
In details, it is presumed that the third preset time is 3 minutes, and it means that the system 10 will continue to send out matching requests when the 3 minutes is up after stopping emitting coupling requests. Moreover, the receiving terminals 14 to be sent matching requests are restricted to be selected from the receiving terminal 14 listed in the identifier list of receiving terminals.
The receiving terminal 14 includes:
a receiving terminal storage unit 140, is adapted to store an emitting terminal identifier of an emitting terminal last paired with the receiving terminal;
a detecting unit 142, is adapted to detect a receipt of a matching request from the emitting terminal 12 last paired with the receiving terminal 14;
a coupling receiver 144, is adapted to detect a receipt of a coupling request, on condition that the detecting unit 142 receives no matching request from the emitting terminal last paired with the receiving terminal; and a receiving terminal wireless transceiver 146, is adapted to determine the emitting terminal 12 corresponding to received matching request or received coupling request as a target emitting terminal, on condition that the detecting unit 142 receives the matching request or the coupling receiver 144 receives the coupling request. And the receiving terminal wireless transceiver 146 is adapted to build a communication connection with the target emitting terminal.
In details, take a smartphone as an example of receiving terminal 14. To be a receiving terminal 14, the smartphone has been paired with a wireless camera, a wireless earphone, and a wireless speaker by coupling request means, and the smartphone only stores one emitting terminal 12 having successfully paired with the smartphone in most recently pairing process, for example, the last paired emitting terminal 12 in history is the wireless earphone, the detecting unit 142 of the smartphone will first detect a receipt of a matching request from the wireless earphone. Because, in real practice, the receiving terminal 14 prefers to continue to pair with the emitting terminal 12 having been successfully connected in previous time. For example, in a communication course between the smartphone and the wireless earphone, except for an artificial breaking down of the communication connection, message signals interrupts, power down, and so forth are the most common causes resulting in communication breaking down. Under such circumstances, the receiving terminal 14, i.e., the smartphone still needs to pair again with the emitting terminal 12, i.e., the wireless earphone successfully paired in previous time after being powered on again or signal recovery, so as to continue previous communicating procedure.
If the receiving terminal 14, such as a smartphone, fails to get the matching request from the emitting terminal 12 successfully paired in previous time, that is the wireless earphone, the receiving terminal 14 will activate the generic pairing mode of the receiving terminal. That is utilizing the coupling receiver 144 to check a receipt of a coupling request. It is preferred that the checking procedure will be paused when a coupling request is detected by the coupling receiver 144.
As shown in FIG. 2, in a preferred embodiment, the receiving terminal 14 further includes a triggering unit 148. When the triggering unit 148 is activated, the coupling receiver 144 executes the step of detecting a receipt of a coupling request.
In present embodiment, the coupling receiver 144 no longer diagnoses whether the detecting unit 142 would receive a coupling request send by the emitting terminal 12 last paired with the receiving terminal 14 or no, and only the triggering unit 148 is activated, the following step is executed: detecting a receipt of a coupling request.
The differences between the embodiment in FIG. 2 and the embodiment in FIG. 1 are described below: in the embodiment of FIG. 1, as long as no matching request is received, sent out by the emitting terminal 12 last paired with the receiving terminal 14, the generic pairing mode will be activated to detect a receipt of coupling request. In the embodiment in FIG. 2, the triggering unit 148 needs to be artificially triggered to activate the generic pairing mode of receiving terminal. The effective results of the embodiment in FIG. 2 lies in: the receiving terminal 14 can not only continue to pair the emitting terminal 12 successfully connected in previous time in priority, but also be capable of initiatively choosing whether to accept coupling requests from all detectable receiving terminal 14 after pairing failure.
In another embodiment, the emitting terminal 12 is engaged with a first device, the receiving terminal 14 is engaged with a second device including a power supply. On condition that an electrical connection is set between the second device and the first device, the second device is adapted to transmit electricity of the power supply to the emitting terminal by the electrical connection, thereby the emitting terminal is powered.
Combined with the above illustration, if the emitting terminal 12 is independently powered, the emitting terminal will continuously send out matching requests or coupling requests unless the emitting terminal 12 successfully connected with the receiving terminal 14, or when a third preset time is up after interruptions, the emitting terminal will repeat a cycle of sending matching requests. Thus, second device engaged with the receiving terminal 104 provides power supply to the first device engaged with the emitting terminal 102 can efficiently conserve energy of the system 10, as elaborated in the detailed embodiment below.

DETAILED EMBODIMENT

In present detailed embodiment, the first device can be a detachable locomotive, the second device can be a detachable container engaged with the detachable locomotive. The receiving terminal 14 can be a display device disposed on the detachable locomotive, and the emitting terminal 12 can be a camera equipment mounted onto the detachable container.
The camera equipment includes an emitting terminal storage unit 120, a traversal unit 122, a pairing unit 124, and an emitting terminal wireless transceiver 126.
Wherein, the emitting terminal storage unit 120 is adapted to store an identifier list of receiving terminals of display devices having been paired with the camera equipment in history.
The traversal unit 122 is adapted to transmit matching requests successively to the display devices in the identifier list of receiving terminals, until the emitting terminal wireless transceiver 126 receives a matching response.
It is preferred that the traversal unit 122 is further adapted to sort receiving terminal identifiers in the identifier list of receiving terminals, according to time tab corresponding to each receiving terminal identifier. The time tab is a history pairing time between the receiving terminal and the emitting terminal in accordance with relating receiving terminal identifier, and the sorting is carried out on the basis of interval values between a history pairing time and a current time in smallest to largest order. It should be noted that if a camera equipment has paired with a display device for many times in history, and only one connection record of the display device is logged in the identifier list of receiving terminals. The time tab of the display device is the history pairing time when the display device is paired with the camera equipment at last time.
It should be clarified, although described above, the traversal unit 122 sorts the identifier list of receiving terminals. In an alternative embodiment, the identifier list of receiving terminals is sorted according to recent history pairing time between the display devices in the list and a specific camera equipment. The traversal unit 122 sends matching requests in accordance with chronological order of recent history paring time to the receiving terminals in the identifier list of receiving terminals.
The pairing unit 124 is adapted to transmit coupling requests to detectable receiving terminals on condition that the emitting terminal wireless transceiver 126 receives no matching response returned by the receiving terminal within a first preset time. In details, mentioned below, when the camera equipment sends out a matching request, after the display device takes over the matching request, the display device will transmit a matching response to an emitting terminal wireless transceiver 126 of the camera equipment sending out the matching request. Therefore, a preset duration is needed, such as 6 seconds, within the time of the preset duration, (from the moment the traversal unit 122 starts to send matching request). If no matching response received, it means that all of receiving terminals in the identifier list of receiving terminals receives or accept no matching request. At this moment, the camera equipment initiates the generic pairing mode, i.e., the pairing unit 124 sends out coupling requests to all detectable display device, until a coupling response is received.
It should be noted that the preset duration is determined based on length of identifier list of receiving terminals and processing speed of the system 10, as long as the camera equipment can send out matching requests to all receiving terminals in the identifier list of receiving terminals within the preset duration.
In another embodiment, in the generic pairing mode, the pairing unit 124 successively sends out coupling requests to detectable receiving terminals. It is preferred that in each pairing process, after a preset time the pairing unit 124 send out a coupling request to a display device available for connection, it is need that the emitting terminal wireless transceiver 126 is detected a receipt of a matching response by the pairing unit 124; if no matching response received, go on generic pairing.
The emitting terminal wireless transceiver 126 is adapted to detect receipts of matching responses or coupling responses, on condition of receipts of a matching response or a coupling response, to determine the display device corresponding to received matching response or received coupling response as a target receiving terminal, and to set up a communication connection with the target receiving terminal.
In a preferred embodiment, the pairing unit 124 is further adapted to send coupling requests in a second preset time to detectable receiving terminals, and to cease sending coupling requests to detectable receiving terminals in condition of no coupling response received by the emitting terminal wireless transceiver 126.
In details, for example, the second preset time is 60 seconds, it means that the system 10 will assign 60 seconds to the pairing unit 124 to send coupling requests, if the emitting terminal wireless transceiver 126 receives no coupling response within the 60 seconds. It is inferred that no display device receives or accepts the coupling requests, and the coupling request process is failed. For energy source saving purpose, stop emitting coupling requests.
In a further preferred embodiment, the traversal unit 122 is further adapted to successively transmit matching requests to display devices in the identifier list of receiving terminals, when a third preset time is up after the pairing unit 124 ceases sending coupling requests to the detectable receiving terminal, until the emitting terminal wireless transceiver 126 gets a matching response.
In detail, it is presumed that the third preset time is 3 minutes, and it means that the system 10 will continue to send out matching requests when the 3 minutes is up after stopping emitting coupling requests. Moreover, the receiving terminals 14 to be sent matching requests are restricted to be selected from the display devices listed in the identifier list of receiving terminals.
The display device includes:
a receiving terminal storage unit 140, is adapted to store an emitting terminal identifier of a camera equipment last paired with the display device;
a detecting unit 142, is adapted to detect a receipt of a matching request from the camera equipment last paired with the display device;
a coupling receiver 144, is adapted to detect a receipt of a coupling request, on condition that the detecting unit 142 receives no matching request from the emitting terminal last paired with the receiving terminal; and a receiving terminal wireless transceiver 146, is adapted to determine the camera equipment corresponding to received matching request or received coupling request as a target emitting terminal, on condition that the detecting unit 142 receives the matching request or the coupling receiver 144 receives the coupling request, and to build a communication connection with the target emitting terminal.
In a preferred embodiment, the display device further includes a triggering unit 148. When the triggering unit 148 is activated, the coupling receiver 144 executes the step of detecting a receipt of a coupling request.
In present embodiment, the coupling receiver 144 no longer diagnoses whether the detecting unit 142 would receive a matching request send by the camera equipment last paired with the display device or no, and only the triggering unit 148 is activated, the following step is executed: detecting a receipt of a coupling request.
